Changelog

Bug fixes - 4.64.2

• A tox environment with env_dir = "{tox_root}/.venv" no longer crashes with FileExistsError after another environment ran (:issue:4090) - by :user:gaborbernat.

  • With :ref:venv_redirect unset, the new default, tox writes the redirect file unless a tox environment lives at .venv; with true, tox fails the run with an error naming that environment.
  • tox deletes a redirect file it wrote where an environment should live, and fails the environment with an error naming any other file there. (:issue:4091)

• The :PEP:832 .venv redirect file now names a deliberate development environment - by :user:gaborbernat.

  • tox picks :ref:venv_redirect_env, else an environment named dev, else the first that installs the project in development mode, and writes nothing without one, so a project that uses tox for tests alone gets no file.
  • tox devenv points the redirect at the environment it creates, and later runs leave it in place.
  • tox tells virtualenv to write no redirect file of its own beside the environments it builds. (:issue:4092)

v4.64.1 (2026-09-24)

---

Bug fixes - 4.64.1

• Apply -x/--override and TOX_OVERRIDE values that target a section the configuration file does not define, such as tox.skip_missing_interpreters on a tox.ini without a [tox] section, instead of dropping them - by :user:gaborbernat. (:issue:4089)

v4.64.0 (2026-09-24)

---

Features - 4.64.0

• Point a :PEP:832 .venv redirect file at a tox environment after each run, so editors such as VS Code or PyCharm pick it as the project interpreter instead of asking you for a path under .tox - by :user:gaborbernat.

  • tox picks an environment named dev, then one installing the project in development mode, then the first of :ref:env_list; set :ref:venv_redirect_env to choose another.
  • tox leaves a .venv directory alone, and a redirect file pointing outside its environments.
  • tox removes the redirect while it recreates the target and writes it back once the run ends.
  • Set :ref:venv_redirect to false to opt out.
  • The feature is provisional while :PEP:832 is a draft: a minor or patch release may change it in backward incompatible ways to follow the PEP. (:issue:4013)
